GARAMEL-VJRAPPING: MACHINE.

Application filed January 9, 1922. Serial No. 527,828.

To all whom it may concern:

Be it known that I, VVALTER H. SERGENT, a citizen of the United States, and a resident of the city of Middletown, in the county of Orange and State of New York, have invented certain new and useful Improvements in a Caramel-Wrapping Machine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to a caramel or candy wrapping and forming machine in which the dough or bulk is fed to a rotary forming and cutter box from which the formed pieces of candy are projected to a wrapping wheel. 1

It is an object of this invention to generally improve and simplify theconstruction and operation of such machines.

It is a further object of this invention to provide an inclosed lubricant containing casing or chamber for containing all the main transmission mechanism intergeared in compact form and having "parallel shafts extending through the rear wall of said chamber and directly connected to the operated mechanisms supported on the rear wall. It is broadly an object of this invention to construct a compact machine occupying but little space.

It is a further object of this invention to provide an improved discharge box.

Vith these and other objects in view, which will become more apparent in the following description and disclosures in the drawings, my invention comprises the novel features of construction and combination hereinafter described and more specifically pointed out in the appended claims.

As shown on the drawings:

In the different figures of-thedrawing, there is illustrated one embodiment of my invention, and in order that the same may be clearly understood, I will describe the different steps in the operation of forming or moulding, cutting and wrapping a piece I is H X .4 I sit candy such a caramel, for exampnr,

r FFIGE.

In' referring to" Figure. there is shown a feed table 1 from which the candy douf of proper viscosity is fed through, the chute 2 into the forming and cutting box 3 (see Figures 4l, 5, 6 and 21). v

Forming and cutting mechanism. The forming box 3 comprises anintermittently rotatable di's'kmember hating a downwardly extending hub or jOLlQDti-l 4. (Figs. l and 5) "rotatably mounted in a socket formed in a 1 supporting bracket c which is attached to the main transmission and lubricantcontaining casing 6 of the machine. The lower surface of the disk is providedwith a bevel gear- 7 which meshes with a beveled pinion 8 secured on a shaft 9 journalled'in the-bracket 5. The shaft 9, which'is termed the forming mechanisi'n drive shaft, is connected to tliiejn'iain drive andintermittently rotated thereby, as will be explained hereinafter. The upper surface ot the disk-3is provided with" radially extending blades 10 (see Figi21) near the outer periphery. In the present instance, these blades are secured in grooves in the upper surface of'the disk and are tapered toward their inner ends to pr'orid a cut ting edge; These-blades are spaced' apart a distance equal to the length-bf the piece of candy desired and'are spaced a'sbort dis tance from the outer periphery ot'the d sk. to provide space for a guard member ll (Fig.4) which encircles the disk 3 and forms in connection therewith a mould or forming box, and to prevent the candy dough from escape-as it is fed from the chute 2 (see Fig. 6) andto direct the ea 'ie under the guard 11, an additional guard 12 is preferably secured to the guard 11 and chute 2 to protect the operators fingers.

As the plastic candy is fed upon the cub tingdisk3 and pa ssesunder the guard 1 or in other words as it is led into the forming box, it is first acted-upon by a presscr foot 13 which presses'or partially presses the plastic candy between the blades 10, and as the: disk 3 is rotated, the candy'is acted uponiby a second presser foot 1a: which COJ'P pletely presses the plastic candy into the moulds formed by the bladeslt) and'guard 11, and at the same'time shears"thesameby pressing against the cutting edgesof' the blades l0, as shown inFigure 21. The presser foot 14' is so constructed that it should onlycomein direct contact with single blade at a time, and to preservethe cutting edge'of the blades an insert of fibre 14- or other non-metallic substance is fixed in a specially provided groove in the pressrr I insert in.

niethod of accomplishing foot so that the blades will strike the fibre. Figure 21 shows the position of the presser feet at the limits of their operative pressing strokes, and it will be noted that prcss r foot 13 is spaced some distance from the cutting I edges of the "blades, while press 1.1- foot l lco'nt-acts 'a single blade at the fibre The presser feet glide over the upper surface of the disk 3 and are connected' for simultaneous operation. One this consists in using a pair ot'cross arms or levers l5and. rig-idly connecting the outer end of each arm to'its respectivepresser foot (see FigsfG and 21) and rigidly connecting the inner end of each arm to a sep'arate vertical operating rod or shaft'lG (see Figs. 6 and 24).- The shafts 16 are referably: supported in tubular bearings N (see'Fig s. and secured side by side to the casing G,the lower end ot'each shaft projecting beyond itsbearing and being provided with a gear segmentjlfk (Figs; 3 and 2d). The two gear segments intermesh in the form of a toggle so thatlhe two shafts 16 are constrained to oscillate sin'iultaneouslyu For the' purpose 0t oscillat ing-"the shafts 16, a crank 19is rigidly cured to one gearsegmentat one end and connected by an adjustable link mechanism 20 at its other end to a wrist pin21'eccentrically mounted on a drive shaft 22 journailed in 'a bearing bo'ss'nfl on'the main frame 6. The shaft 22 is continuously operated from the main driving shaft, as will be hereinafter more fully described.

In order to scrape. and cleanse the cutting blades, a specially coirstructedwiping mechanism hasbe'en provided, as shown in Figures 21 to 23. The inechanisn'i consists of a pair of jaw members2lpivoted intermediate their' endsupon a reciprocating blockor plunger 25 slid'ably-mounted in a guideway"formed' in a support26 secured to the bracket The front part ofthe guide way is enlarged to allow the rear ends'of the aw members to expand so that the wiping elements 27' secured to the forward end thereof may embrace thecutting blades 10, and fort-he purpose of thus expanding-- the jaw men'ibersf 24;, a spring 28 is suitably anchor-ed bet-ween therearends of th'efjaiv members by providing anchoring holes in the inner surfaces thereof; In order! to properly space the front endsot the jaw members, a lug 29 is preferably provided upon thesliding plate 25between the said jaw membersi A pair of guideroll'e'rs'30 or the like are preferably positioned at the upper corners of the enlargedguideway and the rear ends of the jaw members are bevelled so that upon the inward movement of the reciprocating bl ck or plunger 25, the bevelled ends will readily' 'ride up the rollers into the restricted guideway, thus opening the jaw members against the tension of the spring 23. The slidable block 25. is periodically reciprocated by means of a bell crank lever 31 connected by a link 32 (shown in dotted lines inFigs. 22 and'23) to the sliding bloclr25 which is provided with a wrist pin projecting through slot in the lower wall of the guideway. it is evident that the plunger is recipro cated outwardly the wiping elements will pass on each side of the blade and when the outward linjiit cit n'ievement ha. been reached the rear ends oi the jaw members will have advanced to the enlarged guideway which will allow them to expand and press the wipers 27 together so that upon the inward oi, it is only necessary to locate the wiping mechanism in front of a blade when at rest, as each succeeding blade will come to rest at the same point. The crank 31 is connected by suitable linkage 31 to a crank 40 see 3) operated from the main drive. Each intermittent rotation of the cutter disk 3 or forming box brings a formed and cut piece of candy in alineinent with adischarge opening; 34;v in the guard 11 (see l and 5), which is termed the feeding aperture in respect to the wrapping wheel, the cutter disk 3 remaining momentarily at res in such position while an ejector 35 ejects the candy. The ejector 35 is supported upon a pair of parallel links 36 (see Figs. 3 and 4t) which are oscillatably supported on journals 37 secured in the under part of a casting; 38 bolted or secured to the frame 6. and is intermittently operated by means of a link 39 connected to a crank 40 operated from the main drive. as will be more fully hereinafter described.

llrappcr feeding and shearing modernism.

As the ejector 35 ejects the candy through the discharge or feed opening 3 1, the paper feeding; mechanism has fed a wrapper 41 (see Fig. l) in front 'of the cube .or piece of candy. As shown in Figure 4, a roller of wrapping paper is rotatably supported upon a standard 42 on the frame in any approved manner, the paper being trained over the tension pulley 43 to a roller or pulley 44: supported upon an arm 45 secured tothe standard 42 and having" a paper brake 45 resting upon the, paper. From the roller 4%, the wrapping paper passes through a guideway formed by a member 4:6 and a brush h'oldine" member l7 )ivoted thereto at one cnd'and secured at the other by a latch l8 (see Fig. 1.2) on the member 4-6 engagmg a pin on the member 47. A brush 49 is suitably secured to or in the member 47 tobrush the paper as it passes through the guideway and act as a brake to prevent its being pulled back when the paper feed is thrown out. The brush holding mechanism may be variously supported. In the present instanc 'it is provided Witha hollow lug 5 to receive a rod 51 supported in a standa d 52 (see Fig. secured to the top of the r: 3 From the brush mechanism, the p aer descends and enters a paper chute or guideway formedby the plates 53 and 54: which pass through an aperture in a bracket 55 on the inner side of the casting 38 and integral therewith, and extend in proximity to the discharge opening 84:. 'lhe plates 53 small vertical end strips to produce a closed chute (see Fig. As the paper passes through the said guide, it is fed downwardly by means ot the feed rolls 56 and 57 (see Figs. 4 and 17) which extend into apertures in the plates 53 and 5a.

The feed rolls are yieldingly suspended upon a bell sank lever arrangement rotatably supported upon arod58, and having a pair of downwardly extending arms 59.

which carryjournal bearings 60 for rotat ably receiving a shaft 61 to which the rolls 56 are secured. the end of the shaci't being prorided with a small spur 62. The bell crank lever provided with a horizontal aria '33 wl'iich is yieldingly and 'adjustably SNJPOltGfl on a vertical spring pressed. rod (34i- (see Fig. l), the lower end of which is adapted to be actuated for throwing out the teed b an adjustable abutment 65 by' the crank 65 which extends through the outer Wall ot the casting 38 (see Fir 5 and (l) and the upper end or. .c-ends through an aperture in the 38 and into a recess in a nut or cap .LoltLl upon the top oi the casithe swine" H"? b Ig CODilDQfl between the t. p of the cap 66 and. an aluitment on 10 red to which the arm is pivoted. 'l 'he must ruction is ,ich that the spring t tends '0 keep the rolls 56 in yielding; operatire ition with the paper, the bell crank being- 1 'staolo by craul-z G5 to throw out the paper iQ-t-(l by aiiljustingr the rolls 56 away from the aper. The rolls iiOand 57 are preferably provided with wipers (38 which are suitably supported so as to bear upon said rolls.

In order to intermittently operate the rolls it? id to supply a wrapper at the proper Lu.

with e and o i. proper length. variable speed and 54 are spaced apart by 'ineans'o't a-seriesoi stepped gears or a gear coinposedolf a pluralityof gearcircumferences of varying diameter in combination withan adjustable gear for effecting a driving relation bet-ween gear 71 and any of the dii'lerent gear circumferences. As shown in Figures 9, and11, a shaft 72 is mounted in bearings iii-the vertical wall of the casing 6 and the" bearing'wallotthe casing'38 for non-rotatabiy supporting-:21 small spur gear 73 which is periodicallyoperated from the main driving" shaft, as will be hereinafter more fully described and a se-riesof different sized' spur gearswc to 78 and a gear? 9 for a purposeto be later described. F or bringing gear 71 in operative relation with any of the gears T l to 78, there is provideda longitudinallyand radially adjustable gear 80 rotatably supported on awrist pin'81' secured on a crank 82which is secured on a shaft 83 mounted in a bearing in the inner vertical wall of the casing 6 and extends through the outer vertical wall of easing 6, wherethe same is provided with a handle or linob8t(seeFigs. 5 and'G). By grasping thehandle 841, the gear 80 can beraised or lowered 'andshifted longitudinally to eiiect anydesired rate of wrapperfeed desired to securedifi'eren't size-d wrappers. The feed rolls feed the paper down through the chute past'the discharge opening'gej' and when'a sufiicient length has been thus fed, it is sheared ofi at the proper time. For this purpose'a shears has been provided'which consis'tsot a stationary shear plate 85;and

a mov'ableshear plate 86 (see Figsd and 20). I

The stationary'shear plate is supported on an adjustable casting 87 or the like upon one side of a rod 88 which depends from the cast ing 38. A clamping block 90 ispositioned upon the'opposit'e side of therod and securedto'the-casting 87 (Figs; 5 and 20). A screw 89 extending from the casting" 38 into thecasting87 may adjust the latter. The lower edge'of the stationary shear plate is provided with a cutting edge to" cooperate with'th e cutting edge otthe movable shear plate'*'86 which is pivoted upon the under surfaceoftherbloclz or casting 87 and is periodicallyoperated by'the 1ink91 pivot-ed by means of a giinbal joint'or' the like to the inner end thereof. By reterence'to Fig. 4,

it will be noted that the paper chute plate 54 is shortened so that thestationary" shear plate will fit'thereunder, whilethe plate 53 is f' deflected or bent'inwa'rdly to direct the paperagamst thestationary shears. The

operating inechanisnr is'so' timed that the shearscompletethe shearingof the'paper, as

it comes in contact with'the candy discharged At the time when the ejector 35 ejects a piece'of candy through the discharge op en-' ing 3%, it will pick up the wrapper that'has' been fed in front'of the cand as above exv l v H plained', and shown in Figure 2e, and push the combined wrapper and candy into a pocketQS oi a wrappingwvheel 9l-"WlllCli is periodicallyoperated and always "brought to rest with one of its two pocketsin' al' nement with the discharge opening 34 and the other pocket in-alinenient with' 'a discharge boi: 95. The pockets 'in'the wrap ing wheel are diametricall opposite each other, am a separatee ector 96 is slidingly mounted in the wheel adjacent eachfpocke't (Figsjel and 16), the forward end ofeach ejector being provided with a head 97 for"contactingthe candy; while the rear ends are provided with operating heads 98" that slide in guide grooves 94; in the web of 'the' wheel (Flgs. andlSj the operating heads 98 projecting sulli'cientiyoutward in order that they may be contactedby'a pin or abutment"99 car ried by the aforementioned oscillating crank l0, when in position to discharge-a wrapped c'andy'froni apo'clret93; As s r'nvn in FigurelG, each ejector is yieldingly mounted in a shdable bushing 100 having an enlarged bore entering from one end," and teri'ninati'ng short of the other end to provide'an' annular"shoulder; the outer halt'of the ejector rodbeingreduced in diameter to provide 'anannular shoulder, a coil'spring 101 being confinedbetween these shoulders,' andas thebushinglOO is shorter than' th'e distance betweenthe heads of the ejector; the ejector will move relatively tothebushing. This construction permits the ejector head '97 to move a distance outwardly beyond the end of "the'bushinlg and beyondfthe pocket when discharging-a wrapped candy, and as soon'as'the' pin 99 isbeing-withdrawn from. operative engagement with an ejectorhea'd 98, the spring-101 will quickly-snap or withdraw the head 97 from the "discharged and wrappedcandy,until the saidhea d strikes the outerend'ofth'e' 'bushingi This cons rue tion allows the'iinal folders to operate and preve'ntsthe ejectorhead 97 fronrsweeping past the-ejected and wrapped candy when the wrapping wheelrotates, and ejects the candy sufficientlybeyend thewheel so that it cannotcoine'in contact therewith; llrdjll;

thickness of the candy being wrapped. it is contemplated that any thickness of candy may be wrapped from approximately onefourth to threefourths inches in thickness; the sheared wrapper 104, asshown in Figure 25, will then be wrapped around the bottom and sides of abloclr of candy shown in Figure 26.;

lVhile the wrapping wheel 9st is still in. charging position, the first top fold w ll be made by a folder 105 which is in the form of a plate secured to a rock shaft 106 carried by a lever 107 pivoted to the back of the casing 6 and periodically oscillated by means of a yielding pitman 108 connected to said lever 10? intermediate its ends, the lower end of the pitman being slidably mou: ted in a bearing 109 carried by a c: l: 110 which is connected to a shaft 111 intermittently operated from the main drive, as will be more fully hereinafterexplain The lower end of the pitman isprovided with a nut to bear against the hearine- 109 so that upon the upward movement or the crank 110 the total thrust will be tiaasiiii.ttedthrough the spring 109, while upon the downward stroke the thrust will be transmitted to the nut, as is obvious. it is desirable that the folds" 105 be yieldable in directions to and from the wheel and for this purpose the rock shaft 106 is provided with a rank arm 112 having a short rod 113 attached thereto which slides through a bearing aperture in a lug, 11 1 projecting "ruin the lever 107, being constrained from noveinent in an upward direction by means of the nut 115, but being yieldable in a downward direction through the yielding feature of. the spring 116. This construction allows thefolder 105 to yield as itfunctions. 1t willbe obvious that as the shaft 111 is oscillated to raise the folder 105 connected thereto, the front end of the folder will ongage the wrapper at 1045" and fold the same over the topof the block or cube of candy,

shown in Figure 27. 7

As soon the first top fold has been completed, the wheel 94 will rotate in a counterclockwise direction and the unfolded top portion 101 of the wrapper will come under the second top folder 117 which is in the form of curved gravity shoegfitting and, resting upon the upper circumference of the wrapping wheel, being yieldably se- 1\)3 so that the plates; may have cured by a link 118 (Fig. 4;) pivoted to the casting and yieldinglyheld by a spring 119 (see Fig. 11), the folder 117 thus making the second top fold shown in Figure 28. lVhen the wrapping wheel 91- has advanced from the charging positions distance equal toapprow. ua ely or a quarter ofa revolution, it 1 ll stop 'inonientarily with a pocket direcicy under the end tucker inecha nism which consists of a pair of parallel tucking elements 120 (see Figs. 1 and 15) in the form of resilient plates secured at their upper ends to a block 121having a portion fittin in a guide groove '55 in the bracket 55, said block 121 being pivoted to a short link 122 which in turn is connected to an operating crank 123 which is secured to and oscillated by a shaft 121 driven from the main shaft, ashereinafter more fully described. The tucking elements 120 are so spaced by the block 121 that they glide down on each side of the shoe 117 and Wheel when periodically operated in timed relation to the operation of the machine, and tuck the top extending portions 104 and 104: down wardly, as shown in Figure 29. v

As soon as the tucking mechanism has completed its work, it returns to inoperative position and the first end,- folders. 125 (see Fig. 1) come into action. These first end folders 125 are in the form of fingers which rotate and which are mounted and clamped upon short stub shafts 125 which project from the downwardly extending wings 126 (see Figs. 3, 10 and 11) of the casing 38, which win s 126 pass in spaced relation on each side or the upper portion of the wrap ping wheel, as clearly shown in Figures 8 and 1, These first end folders are mounted upon the ends of the stub shafts, which are suiliciently spaced apart to allow the wheel to rotate therebetween. In order to rotate the stub shafts, they are extended through the wings 120, where they are provided with spur gears 12?, one spur 127 meshing with the aforementioned gear 'Z'Sand being rotated thereby, while the other spui gear 127 messes with a similar gear 128 which turn meshes with a similar gear 129 (Fig. 11) secured'to a r0d180 rotatably supported iirbearingsin thewalls of the castingBS. The opposite end of rod 130 is provided with a similar spur gear 131 which meshes with the aforementioned gear 79. As the gears 12?, 128, 129 and. 131 are all similar and of the same diameter, it will be obvious that retation of the gear Z9 will simultaneously rotate both stub shafts and the first end folders 125 thereon. Figure 4, the end folders 125 rotate in a counter-clockwise direction and effect the rear end folds 101 and 10%, as illustrated in Figure 30. As soon as the first end folds have been made, the wrapping wheel rotates again From the position shown in VII . part of the paper reel standard 4-2, as shown in Figures 3 and 4, and are operativelyand yieldably held in contact with the upper sidesofthe wrapping wheel by means of a coil spring 138,.which connects the two folders below. their pivot points and tends to drawthem together against the sides of the wheel. The front edges of these folders are preferably bevelled so that the second end folds can more readily pass thereunder. This second end fold is effected while the wrapping wheel is in motion, the end folds lO iand 104 passing. under the folders 132 and being folded uponand over the first. end folds, as illustrated in Fig. 31.

After traveling through said are of .90", the wrapping wheel comesto rest in discharging position with the caramel pocket in. alinement with the discharge box. 95. Atthis point the crank {t0 will be oscillated in a counter-clockwise direction, the ,pin 99 striking the head 98 of. the ejector and ejecting. the partially. wrapped caramel into the discharge box 95, as shown in Figure 18. After the caramel ,has been ejected, the crank 1-0 will oscillate sufliciently in a clock.- wise direction, allowing thespring 101 to snap the ejector into the positionshownv in Figure 16, where it will not interfere with the finalfolders -134t=(seeFigs. 18 and 1 9) which are pivotedupon thelower end of the paper reel standard Y and j are provided with intermeshing gear segments 185 and l36 at their pivoted ends whereby the folders are constrained to .operate simultaneously. .In'

order to ,operate. the folders, the gear'segment 136 isprovided with-an operating arm 137 having a pitman 138 pivoted thereto, the pitman slidably ,passinggthrougha block 189 on'the crank 140 secured tothe shaft 159projecting-from the hollow bear- Z ing 141, the shaft extending within the casing 6 where it is periodically-driven from themain shaft, aswill be later, set :forth. The pitman 138 extends some distance below the crank block l89,. having an adjustable nut on its end for confining a coil spring .142 againstv the block 189. This :construction produces a yieldable pitmanjfor operating the last folders, as is obvious, and the tension of the spring may be adjusted at any time. When the. wrapped caramel is being [ejected the folders 134: are widely separated and donotiinterfere withthe discharge of the caramel, but directly after the discharge of the .,caramel, the ,said folders are operated so as to close or come together whereby they engage =the-lower side tucks lOl and fold them;.against the bottom: of the wrapped block of candy, ;as shown inFigure 32, thereby firmly binding the endfolds against the candy. Ifdesirable, one end folder may be set slightly inadvance of the other to prevent jamming of the points of the v -shaped tucks,1 ()4c and for obtaining a ,good overlap.

"Discharge bow.

l-Vhile the final vfoldersare operatingto make the final foldsesabove described, the wrapped. candy is held; in the discharge j box 95-(see ;Figs. 3, 4Landl8)..gThis box comprises a fouresidedstructure having a passage therethrough to receive the iwrapped candy, the passage bfling lined onthe top andsides with resilientplates 1 13 pivoted or hinged to blocks ,l3 fastened ,on the outer ends of the sides and top andybent or deflected inwardly attheiriinner ends,

coil springs 144- being-positioned in ,sockets formed in the walls of the box to yieldingly bear against thespring plates to slightly force the-inneriends inwardly so that the Wrapped candy will be securely held while the final. folds are being made. If desirable, the springsocketsmay, extend through the box walls and be closed by adjustable screws 1 14 for varying the tension, of the spring, and. the bottom of the box is provided with a smooth base plate 145. Thedischarge box is supported upon aibracket 1&6 mounted upon a projecting stud 147 extending from the rear of the casing 6. ,Onlyaportion of the length of the box rests ,upon the bracket 1 16; the remainder of the length of, thebox projects downwardly forming a shoulder which bears against the outer side of the bracket .146, and a rod 14:8 is secured in the bracket and freelypasses throughan aperture inthe shoulder of. the boxand projecting some distance .therebeyond. The outer end of the rod is provided with nuts or the like for. confining a .coil spring, 149. on .the

rodagainst the shoulder of. the ,box, and an operating handle 150 is secured .to the lower side oflthe shoulder whereby the discharge box maybe slid outwardlyflon the rod against the tension of the spring. The discharge box. is hence yieldinglymounted for lateral movement and. will give if necessary under he action of the. ejectors 96. The bottom of the ,box projects outwardly to form av ledge 151. which has a groove'or recess in alinement with a ,vertical plane throughthe center ofthe discharge box for receiving a corresponding lug on the bottom of a dischargechute 152, a small rod 153, passing. through the ledgeand lug to holdthe chute in proper relation with the discharge box.

Driving mechanism.

The different mechanisms heretofore. de-

scribed are all intermittently operated in timed relation by the main drive, as will now be cescribed.

In referring to Figure 7 which shows the assembly of the driving mechanism enclosed in the c 6, by means of a cover 6, it will be observed that the shaft 15 1 is the main drive. This shaft extends beyond the front wall of the casing where it is supplied with an operating pulley 156 and a loose pulley and is journaled in bearings supported by the walis of the casing 6. The pulley may be rotated by a belt 155 connected to a motor 155 (see Fig. 1) secured to a bracket near the bottom of the machine frame, and a belt shifter 155 extending through the machine frame may be used to shift the belts. A small spur gear 157 is secured to the main drive shaft 154: and meshes with a large gear 158 secured upon the aforementioned shaft .22 which operates the presser feet in the forming box, the shaft 22 being supported in bearings 160 and 161 (see Fig. 13) in the casing 6. The gear wheel 158 is provided with cam grooves 158 and 158 in each face. The near side cam groove 158 (Fig.

7) operates a bell crank lever 162 secured to a shaft 163 which extends through the casing 6 and carries the rock lever 40 which operates the ejectors and knife wipers. The

other end of the bell crank lever is connected by means of a rod'164 and a crank 165to a shaft 159 which extends throughthe casing 6 and the bearing 1 1-1 projecting from the rear'thereof (see Figs. 3 and 19) and has attached thereon the aforementioned crank 92 which in reality comprises a double crank or two cranks, one of which designated 1 10 operates the final folders and the other, designated 92, operates the paper shears.-

Thecam groove 158 in the far side of the gear 158 is best shown in Figures 8 and 13. The same operates a rock lever 167 which is secured to the aforementioned shaft 111 which operates the vfirst top folder mechanism (see Figs. 3 and 4-). I

Mounted in the casing 6 above the gear 158 is a Geneva gear driver 168 which is mounted upon a shaft 169 supported in the rear wall of the casing 6 and has secured thereon a. spur gear 169 meshing with the gear 158. This Geneva gear driver operates a Geneva gear 170 which is constructed for intermittent arciform movement of 90 for each operation of the driver, being provided with four radial grooves 90 apart for this purpose in which the roller on the driver operates. The Geneva gear 170 is mounted on a shaft 171 which extends through a long bearing 172 projecting from the rear of the casing 6 and supports the aforedescribed wrapping wheel 94 (see Fig.

On the shaft 22 adjacent the front wall,

there is secured a second Geneva gear driver vided with four radial grooves 90 apart and is hence operated through an arc of 90 for each operation of the, driver. A spur gear 17 6 is secured upon the shaft 175 and meshes with a gear 177 supported by the rear .wall' of the casing. The gear 1'77 meshes with the aforementioned paper feeding gear 73 that is mounted on the shaft 72 of the paper feeding mechanism. The gear '73 is relatively small and provided with a wrist pin-178, to which is pivoted'one end of a pi'tman' 17 9, the other end of the pitman being slidably and yieldingly mounted in a bearing on a crank 180, a nut on the outer end of the pitman bearing against one side of the crank bearing and a coil spring 181 bearing against the inner side of the crank bearing. The crank 180 is secured to the aforementioned shaft 124 that operates the top tucker-s (Figs. 3 and 41-).

A small spur gear 1652 (Figs. 5 and 7) is secured to shaft 175 on the far side of gear 176, with which it may beintegral, and meshes with a spur gear 18-3 secured on the aforementioned forming mechanism drive shaft 9, as clearly shown in Figure 5, to rotate the cutter and forming box.

The operation is as follows:

The shaft 15% may be driven by any suit able source of power to impart its motion to shaft 22 through the gears 15'? and 158. Shaft 22 is constantly rotating and hence the presser feet 13 and 1 1, which are op-' erated by shaft 22, will be constantly operating for the purpose of pressing the candy dough between the cutting blades 10 of the forming box for moulding the same, and the presser foot 14 cutting the blocks or cubes of candy as it successively comes into substantial contact with each blade 10, as previously explained. The construction is such that the presser feet make complete oscillations forward and backward during the rest periods of the forming and. cutter D631 3, the presser feet being substantially atthe limits of their inrmerative strokes whenthe forming box or disk 3 is rotated. The forming box 8 is periodically rotated through a space equal to the distance be tween two blades 10; the ratio of driving gears for operating the forming box is such that the forming box 3 is rotated the proper distance'during each 90 movement of the Geneva gear 174.

Assuming now that the parts are in the powheel having onepoclret in alinement with the discharge opening in the forming box and the other pocket inalinement with the discharge. box, and a cut block or piece of sicionshown in the drawing, the wrapping candy being in the mould or, in other words, between the blades 1.0 infront of the dis chargeor fee-d, opening 3%,, and the driving shaft 15 1- is rotated in a counterclockwise direction, the first operation will be pro duced by the nearside cam...groove in gear 158 which operates bell crank lever .162 and shaft 163 .uponWvhich tlieabell crank lever is secured. ..l.he..said .caingroove will first operate snaft 163m a clockwise direction, swinging rod 16 i and crank 165 (see 7) downwardly. crank 165 swings downwardly, it rotates shaft 159 to which the paper shear-sand the final folder jaws are connected, opening or separating the said folder jaws and operating the she rs 86 for cutting off a proper wrapper, and. rotation of the'shaft 163 in said clockwise direction will oscillate crank 10 in the same direction to simultaneously operate the two ejectors for charging a piece .ofcandy and its wrapper into the. pocket of the wrappin wheel and discharging one from the wheelinto the discharge b01195, assuming that a candy has just been wrapped in a previous operation. and at the same time reciprocati the cutter blade wiping mechanism into a position where the wiping elements 27 engage the knifeedges of the blades 10, as shown in Fig. 23. Further movement .of the cam gear158 in the same. direction will operate bell crankcamlever 162and shaft 163 in a reverse direction. This reverse. movement will simultaneously .move the paper shears to. the inoperative position shown in the drawing, reciprocate the wiping elements to cleansea blade 10, move the chargingejector back to its inoperative. position and closing the jaw folders 13%, thespringlOlsnapping or withdrawing the dischargingejector inwardly until its head 9T rests upon the bushing so as not to interfere with the folder jaws .as soon as the pin 99 releases the ejector.

the far side of cam gear v158 will be brought into position to oscillate rock lever 16? for oscillating shaft 111 to operate the first top folder for applying thefirst top fold.

This anti-clockwise rotation of cam gear 158 caused by the above operations will bring the first Geneva gear driver 168 into position for turning the Geneva gear 111') and will bring the roller on cam lever 162 into the dwell port-ionof the cam groove. Rotation of .Geneva gear 170 will rotate the wrapping .wheel 91 a quarter revolution, 90", which .isinounted on the sameshaft 171 as supports the said Geneva gear. As the wrapping wheel is thus rotated, the second -t0p fold will be made by the folder shoe 117,

the wheel coming to rest with the pocket directly under the tucker elements 120. Fun ther movement of cam gear 158 willnow bring the second Geneva gear driver 173 Durin this reverse movement 0 ofbell crank lever 162, the cam groove on into position to rotate the Geneva gear 174 for a quarter revolution while the lirst Geneva gear is locked from rotating by the driver. Rotation of Geneva 17% will rotate gears176 and 18.1, which simultaneoiisly operate gear 183 for rotating the forming box 3, and gear 177 which in turn operates the paper feeding gear 72:3.which in turn oscillates the top tucker shaft 12-lthrough the ieldable pitinan 179. The operation of. gear 188 will bring a fresh piece of candy in front of the discharge o1: ening-8l,and the rotation of 73 will operat the paper rolls 56 and 57 through the gears 7 75, 76, 77 or 78,80, 71, 69 and 62, as before miplained, to feed the paper in front of the discharge openingS-l. 'lherotation of gear 73. willalso rotate the: end folders. 25 through thegears 79,127, 131, 129 andl28. The oscillation of shaft 12% will move the tucker elements downwardly to apply the upper .end tucks 104i and 104;. The gear 73 is rotated one complete.revolution during each operation, so it withdraws the tucking elements 120 during the last 180. of its rotation, and it withdraws the same before the end folders complete their revolution and strike the .rear endsof the wrapperso no interference can occur during the operation of the-said end folders. The cam gear 158 has also rotated. sufficiently to bring the first top folder mechanism into stationary position.

lVlien the cam gear 158 has operatedthe second Genevagear 174 a quarter of a revolution, it will become locked by the locking portion of the driver and the first Geneva gear driver 168 will then be substantially in position to again rotate the'Genev-a gear 170. Further movement'of cam gear 158 will then rotate Geneva gear another quarter turn and rotate the wrapping wheel likewise to bring the pockets into alineinent withthe discharge opening 34 and the dis charge boX 95. During this movement of the wrappingwheel, the second end fo ds will be made by the second end folders 132, as previously explained- This last movement of the cam gear 158 will bring the parts back into the position shown in the drawings, and furtheranovement of the cam gear158 will operate the bell crank cam lever- 162 as previously explained to operate the shears, eject a fresh piece of candy from the forming boi: into the wrapping 1 wheel, eject the wrapped candy from the wrapping wheel, operate the cutter wipers, and separate the final folders which come together and fold the bottom tucks against the bottom surface of wrapped candy, as shown and previously explained.

It should be noted that after thebell crankcamlever 162 has completed its operation, it comes to rest with its cam roller inthe dwell of the cam groove, and at this
